Luther star Idris Elba has suggested there could be a fourth series of the crime drama if the audience demanded it.

The creator of the series, Neil Cross, has previously said that he plans to wrap up the drama series and is considering launching a movie spinoff.

Elba said "My personal ambition is to see this [turn] into a film. But I'm very loyal to the audience that have been very loyal to us.

"If the audience demands another season, or some sort of variable on that, then it should happen, I think."

Elba has also said that the planned Luther movie would be a prequel to the drama series based on Cross’s 2011 novel Luther: The Calling saying "[The film] starts at the beginning of who Luther is and where he's come from."

The third series of Luther starts on BBC One on Tuesday, July 2 at 9pm.
